Abstract (en)
[origin: WO9630156A1] A laser welding apparatus for clad welding the interior surface of a tube includes a rotating sleeve that encloses a fiber optic cable. A stationary laser (100) generates light energy for the welding operations performed by the rotating sleeve (324). An optical coupler (342) is positioned between the laser and the rotating sleeve (324). A rotating cable interface assembly (320) receives the collimated and focused light energy from the fixed optical assembly and applies it to the fiber optic cable (340), which delivers the light energy to the interior surface of a tube (20) to produce a clad weld. The rotating cable interface assembly includes concentric alignment device (480) and a monitoring cavity (502) to provide optical feedback regarding the alignment between the fixed optical assembly and the rotating cable interface assembly. The rotating cable interface assembly (454) may be constructed to include a safety fiber optic (520) with an accompanying safety fiber optic photocell (522) which is used to assess whether excessive light energy from the laser is being used.
